SLIDING MULTIPLE sAsH wINDow'oR DOOR Filed Feb. 4, 1951' INVENToR. F14/9, Ayez/arme Joh/fs/K/EFE@v Hfs A TToe/ve' Y nited E S This invention relates generally to sash frames and sash members and more particularly to metal sash frames of extruded aluminum.

The principal object of this invention is the provision of an extruded aluminum sash frame for laterally sliding windows or doors tvvherein the lintel and sill portions are the same structures. One being inverted and each has a series of spaced parallel rails forming grooves to receive the sash therebetween and are from a cascade from the inside to the outside of the opening.

Another object is the provision of a head on each of the rails in the lintel and sill sections providing an under shoulder to reduce the wearing surface adjacent the sash and provide an engaging surface for wheels supporting the sash. Wheel engaging surfaces on said rails are eq=ual distance from the bottom of the groove so that the -wheels on both sides of the sash are on the same elevation.

Another object is the provision of a shoulder on the Outer face of the shortest flange of the lintel and sash section for receiving one edge of an angle, one leg of which provides a marginal supporting flange and the other leg provides additional rails with additional grooves therebetween to increase the number of sash carried by the sash.

Another object is the provision of a lintel and sill section sash frame, a cross section of which is in the form of a channel. The flanges of which project outwardly and have marginal feet for supporting and sealing the same on the structure carrying the sash frame of the window.

Another object is the provision of lintel and sill sections of a sash frame having spaced parallel rails forming grooves to receive sash which rails are in the form of a cascade, the ends of the sill and the lintel sections being matched with jamb sections having aligned rails forming grooves, which rails lie in parallel planes and are not cascaded. Their object is the provision of an extruded sash frame for supporting a plurality of laterally sliding sash members with interlocking marginal sealing and locking angles along the adjacent surfaces of their alternate vertical edges which permit the adjacent sash members to interlock when extended and be accumulated on either side of the sash frame. When the sash members are extended with their marginal sealing and locking angles interlocked, only the remote sash members need be locked to prevent the opening of the window, the intermediate sash members becomining locked orwing to the inner engagement of their vertical sealing and locking angles.

Other objects and advantages appear hereinafter in the following description and claims.

The accompanying drawings show for the purpose of exemplication without limiting this invention or the claims thereto, certain practical embodiments illustrating the principles of this invention wherein:

Fig. l is a view in vertical section showing the lintel 2,897,552 Patented Aug'. 4l, 1959 and sill and sash members of the structure comprising this invention.

Fig. 2 is a view in horizontal section of the structure shown in Fig. l.

Referring to the drawings the lintel section 1 and the sill section 2 are extrusions, each being made in two pieces 3 and 4 so as to extend the width of the opening. The pieces 3 are channeled in cross section having the web 5 and the outwardly projecting marginal flanges 6 and 7. The outer edge of the flanges 6 and 7' are provided with the marginal feet 8 and 9 respectively. As shown in the drawing these flanges t over the sill, lintel and sill members 10 which have the inwardly extending section 11 providing the inner and outer surfaces 12 and 13. The lintel and sill 10 and 11, the sill having an inner surface 12 and outer surface 13 whereas the lintel has these surfaces reversed with the ywide surface 14 and the narrower surface 15 forming the outer surface. The lintel and sill sash frame sections are provided with the inwardly extending rail members 16, 17, 1S, 19, 20, 21 and 22. The rail members 21 and 2.2 being on the inner member 4 which has the outwardly projecting ange 23 and the foot 24 at rest on the same surfaces of the foot 9. It will be noted that the lintel frame section is the same as that of the sill but is inverted and the cascade is in the opposite direction so that each of the sash members that iit in the grooves between the inwardly extending rails are of the same dimension.

Each rail 16 has a head as indicated at 25 which extends toward the adjacent rail to provide an under shoulder 2'6. The rails 17 have a head 27 which provides two under shoulders 28 and 2.9. The shoulder 28 is equal to and opposite the shoulder 26 and is arranged to be engaged by a wheel carrying the sash member that operates in the groove formed between the rails 16 and 17. Each of the other rails are provided with similar shoulders 28 and 29 for the same purpose with the exception of the rail 22, the head 30l of which is provided with only one under shoulder 31 in a manner similar to that of rail 16 to thereby complete the grooves in these structures.

The feet 8, 9 and 24 are ordinarily provided with openings to receive screws or bolts for the purpose of securing the frame to the frame support 10 and 11. If the pieces 3 and 4 of the lintel 1 and the sill 2 are formed integral with their respective jambs 32 and 33 then the frame supports 10 and 11 are the only members that need be fastened together to secure the sash frame in position.

The ends of the sill and the lintel are matched with the jamb sections 32. and 33 which also have aligned rails as shown extending vertically in Fig. 2. The rails and grooves of the jamb sections 32 and 33 lie in parallel planes and are not cascaded as are the lintel and sill. The jamb members are also in the form of a channel made up of a web with matching outwardly extending marginal anges. The inwardly extending rails of the jambs are of uniform depth and match the rails of the lintel and sill.

Referring to Fig. 2 the sash members 34, 35 and 36 represent the inner series of three sash members and the sash members 37, 33 and 39 represent the outer series of three sash members. Each corresponding sash member of the two series is the same and the sash members 34 and 37 have on their right side a vertical sealing and locking angle 40. A similar angle is shown on the sash members 35 and 38. However these sash members also have the oppositely disposed locking and sealing angle 41 as do the sash members 36 and 39. Thus the intermediate sash members whether there be one or several as indicated at 35 or 38 has both the sealing and locking and if the remote sash members are bolted as indicated by the bolt members 42 a'nd 43 to the sash frame then '11i-he whore eff-the window/'l1 beemesfioekd es@ theL intermediate sections cannot move owing to thiriiitrlocked *sealing-angles.

As shown in Fig. l, eachsash member'is supported on twowlieels asin'dicated'atA g44and1'45. "The'fssh mem- Vbers-34',35,-*a'iid `36 are supported 'on wheels. *wheels ride onthe under shoulders of thelheadsv of the 'j'i'ailsandVV thus Vsuspendthe sashme'n'iher from the lintel. f The sash members Y37,138 -andf39-aref`similar inconstruc tionf-in that the Wheels`34and 35ia're iii-the bottom section of the'sash and" thus support thesash'troml-the sill rather than-the lintel. frAt some placeiial'ong-theflength of the 'frail the 'head' is provided Withenotch so as to permitthe 'Asashto be withdrawn from the'sashtrame.
